 @item --database=@var{path}
 @itemx -d @var{path}
 Instead of searching the default file name database, search the file
 name databases in @var{path}, which is a colon-separated list of
 database file names.  You can also use the environment variable
 @code{LOCATE_PATH} to set the list of database files to search.  The
-option overrides the environment variable if both are used.
+option overrides the environment variable if both are used.  Empty
+elements in @var{path} (that is, a leading or trailing colon, or two
+colons in a row) are taken to stand for the default database.
 
 @item --existing
 @itemx -e
 Only print out such names which currently exist (instead of such names
-which existed when the database was created).

+@code{find}; the use of @samp{-P} is recommended over @samp{-H}.
 
 @item --ignore-case
 @itemx -i
 Ignore case distinctions in both the pattern and the file names.
 
-@item --null

-Results are separated with the ASCII NUL character rather than the
-newline character.  To get the full benefit of the use of this option,
-use the new locate database format (that is the default anyway).
-
-@item --count
-@itemx -c
-Just print the number of results, not the results themselves.

 @item --limit=N
 @itemx -l N
 Limit the number of results printed to N.  If you use the
 @samp{--count} option, the value printed will never be larger than
 this limit.

 @item --wholename
+@itemx -w
 The specified pattern is matched against the whole name of the file in
 the locate database.  If the pattern contains metacharacters, it must
 match exactly.  If not, it must match part of the whole file name.
 This is the default behaviour.
